N. Y., A CORPORATION OF DELAWARE PRODUCTION OF COLORED RESISTING EFFECTS No Drawing. Application filed June 24, 1930, s

The present invention relates to the production of colored resisting effects under ice colors by means of leuco ester salts of vat dyestufis. According to the invention the goods are impregnated with any azo coupling component (such as an arylamide of 2- hydroxy-3-napht-hoic acid, a naphthol or one of the derivatives of l-hydroxy-naphthalene- 4-carboxylic acid described in U. S. Patent 1,453,660), then the impregnated goods are imprinted with a printing paste containing an ester salt of a leuco-vat-dyestulf, an insoluble chromate which when acidified is capable of producing chromic acid and an alkali sulfite. Then the printed goods are dried and, without being previously steamed, developed with any diazo-compound, acidified and finished in the usual manner.

The favorable result attained was not to be foreseen because of the possibility of a mutual detrimental effect between the reducing alkali sulfite employed as a resist and the oxidizing chromate.

In order to further illustrate my invention the following examples are given, the parts being by weight and all temperatures in centigrade degrees, but it is however to be understood, that my invention is not limited 0 to the particular products nor reacting conditions mentioned therein.-

Examne 1 I mpregnatz'ng bath 15; grams of 2.3-hydroxy-naphthoyl-aniline 22.5 cc. of caustic soda lye of 34 B. 20 cc." of monopol-brilliant-oil are made up to 1 liter Resist of yellow to U. S. Patent 1,564,584

eria] No. 463,584, and in Germany J'u1y.5, 1929.

10 grams of glycerol 41.6 grams of boiling water 80 grams of starch-tragacanth-thickenlng grams of mucilage of tragacanth grams of lead chromate grams of a solution of potassium sulfite of B.

200 grams.

Developing solution 20 grams of the diazonium-chloride of 4- amino-4-methoxy-diphenylamine grams of Water liter.

EXAMPLE 2 The goods are impregnated according to Example 1 and printed with the following:

Resist for blue 16 grams of the ester-salt of hexa-bromindigo 10 grams of glycerol 45.6 grams of boiling water grams of starch-tragacanth-thickenmg 10 grams of mucilage, of tragacanth 14.4 grams of lead chromate I 14 grams of a solution of potassium sulfit'e of 45 B.

200 grams.

The goods are further treated according to Example 1.

Light blue efl'ects on dark blue are thus obtained. EXAMPLE 3 The goods are treated according to Example 1, there being substituted for the resist the following resistfor yellowislvgreen.

-5 grams of the estersalt of para-dichloro-dianilido-benzoqu'inone grams of the ester-salt of the dyestuff prepared by oxydation of diben- Zanthrone followed by ethylation grams of glycerol grams of boiling water 80 grams of starch-tragacanththickenin" 10 grams Zr mucilage of tragacanth 11. 3 grams of barium chromate 22 grams of a solution of potassium sulfite of 45 B.

The goods are dried, further developed with the diazo-solution according to Example l and finished in the sameway. Yellow green effects on blue are thus obtained.

grams EXAMPLE 4 The goods are impregnated according to Example 1, printed with the resist of Example 3, dried and then developed with a diazosolution containing 10.5 grams of 5-nitro-2- toluidine per liter, to which sodium acetate has been added, and further treated as described in Example 1.

Yellow-green eifects on a red ground are thus obtained.

EXAMPLE 5 The goods are impregnated according to Example 1, printed with the resist of Example 3, dried and developed in the following:

Piazza-solution is made up to 1 liter.

cc. of water, are added and the whole By working according to Example 1 yellow-green effects on a violet ground are obtamed.

ExAMrm 6 impregnating bath 22. 5 grams of ,B-naphthol, 2') '3 4 grams of caustic soda solutionof34 B. grains of Turkey red 011, made up to' 1 liter.

The goods are impregnated with this iin pregnating bath, dried and printed with the resist of Example 1. After drying, the godds are developed in a diam-solution containing 21.5 grams of para-nitraniline per liter, to which sodium acetate is added, and finished in the same way.

In this manner yellow effects on a red ground are obtained.

EXAMPLE 7 The goods are impregnated with the following Impregnating bath 15 grams of 4-hydroxy-naphthalene-1-phenylketone 10 grams of caustic soda solution of 34 B. 20 grams of Turkey red oil, are made up to 1 liter; they are then dried and printed with the resist of Example 2, dried and developed in a diazosolution containing 8 grams of ortho-phenetidine per liter, to which chalk has been added, and finished as described above.

Blue effects on red are thus obtained.

EXAMPLE 8 impregnating bath 15 grams of 2.3 hydroxy naphthoyl 5 chloro-2-toluidine grams of caustic soda solution of 34 B.

20 grams of Turkey red oil, are made up to 1 liter.

The goods are impregnated with this impregnating bath, dried and printed with the following Resist for'blue 16 grams of the ester salt of tetra-bromindigo, 10 grams of glycerol 32.7 grams of boiling water grams of starch-tragacanth-thickening 11.3 grams of barium chromate 60 grams of a solution of potassium sulfiteof 45 B.

200 grams. After drying, they are developed in a. diazosolution containin 19 grams of -chloro-2- toluidine hydroch oride per liter, to WhlCh sodium acetate has been added, acidified and finished in the same way. 5 Blue effects on a red ground are thus obtained.

I claim 1. Process which comprises impregnating textile goods with an azo coupling component, imprinting the impregnated goods with a printing paste containin an ester salt of a leudo-vat-dyestufi, an insoluble chromate which when acidified is capable of roducing chromic acid and an alkali sulfite, rying the printed goods, developing them with any diazo-compound, acidifying and finishing them in the usual manner.

2. The process which com rises, impre nating textile goods with 2.3- ydroxy-nap thoyl aniline, imprinting the impregnated goods with a printing paste containing the ester salt of leuco 3.4.8.9-dibenzpyren uinone, lead chromate and potassium su te, drying the printed goods, developing them with the diazo compound of 4-amino-4- methoxy-diphenylamine, acidifying and finishing them in the usual manner.
